MAIN: SUSTAINABLE CONSTRUCTION FOR INDUSTRIALIZED DETACHED HOUSE, SUB: ROLE OF RESOURCE RECYCLE FACILITY

misbe2011 Tracking Number 146

Backgrounds The industrialized house is a house which applied an advanced industrial technology to the production. In Japan, the effectiveness of the applied technology has been demonstrated. However, the difference of productivity among construction projects is pointed out (Wu et al., 2008). Construction sites in the central area of Tokyo are small. There are no stock yards at construction sites. A general contractor is starting to adopt a little collection of industrial wastes from small projects (Hamada et al., 2004). The comprehensive logistics for detached house projects is necessary. Moreover, some industrialized detached house manufacturers have set up resource recycle facilities. Objectves The main objective of this research is to analyze the actual function and effect of resource recylcle facility in a Japanese industrialized detached house manufacturer, and to propose the comprehennsive and efficient resource recylce system from the standpoint of economic and environmental assessment. This research surveys the kinds of waste separation and their quantities at construction sites to make clear the effort at sites for industrial waste disposal. Then this surveys the waste separation and recycle system at resource recycle facility and analyzes the effectiveness of the facility established by house manufacturer itself. Research Method The survey institute is a Japanese house manufacturer M. It has built the industrialized houses on the basis of Japanese industrialized system with the wood panel bonding construction method. The structure of house is mainly composed of floor panels, wall panels and roof panels. The panels are manufactured in the factory beforehand, and are joined with glue at construction sites. Nailing and screwing is necessary as a finishing operation. After the shell of the building with the panels is erected, the desired finishes are applied to both inside and outside. On the outside, the plywood is often covered with the siding. On the inside, the fabric is often applied. This research compares the former industrial waste disposal sysytem and the current industrial waste disposal system with the resource recycle facility of house manufacturer M. First, this surveys 4 construction projects as the former system, and makes clear the kinds of waste separation and their quantities at construction site. How to dispose industrial waste outside construction sites is also surveyed. Secondly, this analyses the operation results of the resource recycle facility built in 2009 as the current system, and makes clear the effectiveness of more kinds of waste separation at the resource recycle facility. Finally this discusses the role and function of the resource recycle facility established by the house manufacturer itself.
